yes
no
tl;dr Don't do this. Use ADC1 for analog reads.

Thank you very much for your help.

Short answer is no. The radio uses the ADC2 exclusively.

Thank you for your information. By using the word "radio," are you referring to both Bluetooth and WiFi?

And do you have any idea if adc_oneshot_read() will work for ADC2 when Bluetooth is on?

Thank you very much for pointing me to the post.

I am programming ESP32-WROOM-32D with Arduino IDE. In this website ( https://docs.espressif.com/projects/esp-idf/en/v4.2/esp32/api-reference/peripherals/adc.html#:~:text=The%20ESP32%20integrates%20two%2012,15%20and%2025%20%2D%2027). ), it says that the ADC2 module can only be used when WiFi driver ...

Hello everyone,

I am programming an ESP32 with Arduino IDE. Due to my specific application, my program reads analog signals from 8 ADC pins sequentially, just like the following code shows:

adc[0] = analogReadMilliVolts(15);
adc[1] = analogReadMilliVolts(25);
adc[2] = analogReadMilliVolts(32 ...

Thank you for your reply. Could you let me know how to modify the partition scheme?

Hi,

I read from documents that ESP32 should have at least around 4 MB of flash memory. However, after I compile codes in Arduino IDE, it says that my "program storage space" is only around 1.3 MB. I wonder if this is a normal situation.

I would also like to ask if it is possible to use more flash ...

Hello Espressif Community,

I have two questions related to the PWM hardware of ESP32:

1. By the documentation of the LEDC library, there are 4 timers and 16 PWM channels in ESP32. I would like to ask if all of the 4 timers are ticking at 80 MHz (assume all prescaler is 1).

2. I know that the ...
